A member asked:

Hi. my son got administered bcg at 4 weeks on the 9th sep 19 which was last week. i read that after a week there should a blister and eventually a scar. looking at my sons right shoulder, there is no blister. what does this mean?

Dr. James Ferguson answered

Patience: The blistering is expected to appear at 2-4 wks. No reaction at all would suggest a failure to respond to the vaccine. A conversation with his doc about a repeat would be in order but it is too soon to think that at this point.
